'IPAPER-STOCK-TREATING MACHINE.

Specification of Letters Patent. Patented June 20, 1922.

Application filed September 1, 1920. Serial No. 407,468.

To all whom may concern Be it known that I, MILTON C. J. BILL- INGHAM, acitizen of the United States. re-

sidin at Kalamazoo, county of Kalamazoo, x tate -of Mlchlgan, haveinvented ceraction.

Second, to provide an improved disintegrating or defibering machine welladapted for the treatment of printed papers and deinking the same andpreparing the same for paper stock which produces a superior product.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Fig. I is a detail View partially in vertical central section of a stocktreating machine or apparatus embodying the features of my invention.

Fig. II is an inverted view of the perforated disintegrating plate.

In the accompanying drawing, I have not attempted to illustrate ormaintain the proper relative proportions of parts as these will bevaried to suit the capacity and the particular conditions-ofinstallation of the machines andI also show various parts inconventional form.

In the embodiment illustrated I provide a cylindrical tank 1 disposedvertically and hole 4 therein. This manhole is provided with a cover 5,the attaching means for the cover being shown conventionally at.6.

The tank has a central discharge indicated by dotted lines at 7. Thedischarge pipe 8 of the tank is connected to the inlet 9 of the pump 10.The supply connection 11 is provided for the stock to be treated. Thisconnection is controlled by the valve 12, the pipe 8 being provided witha valve 13.

v The pump discharge 14 is provided with a discharge connection 15 forthe treated stock controlled by the valve 16, and with a discharge pipe17 disposed centrally through the openings 7 in the tank and having anozzle 18 at its upper end delivering near the top of the tank andcentrally thereof.

A foraminated concave plate 19 is supported above the nozzle so that thestream from the nozzle strikes the plate. The plate 19 is suspended fromthe manhole cover 5 by means of the hangers 20. The holes 21 in theplate 19 are preferably-tapered as illustrated.

The pump is driven from an electric motor indicated at 22.

With the parts thus arranged the stock to be disintegrated is deliveredfrom the nozzle 18 against the plate 19 and is driven through the holesin the plate so that the fibers are pulled apart and separated, thestock being circulated as long as may be desired.

My improved disintegrating or defibering machine is not likely to clogas any pieces of string or the like which strike the plate fall backinto the tank and further the stream impinges against the plate forciblydriving the stock through it keeping the openings comparatively free.The upper walls of the tank are curved so that the stock is deflecteddownwardly within the tank around the walls and this'insures a completecirculation of the stock which is of importance as should a portion failto circulate for a time and then become lodged, the stock is notuniformly disintegrated and is not suitable for the purposes intended.

My improved machine is especially well located manhole therein, a coverfor said manhole, a pump having its intake connected to said tankdischarge, a discharge pipe for said pump disposed through salddischarge opening centrally and vertically of said tank and providedwith a discharge nozzle positioned at the upper end of the tank, and ahorizontally disposedconcave foraminated plate suspended from saidmanhole cover above said nozzle to receive the stream therefrom. 4

I 2. In a stocktreating machine,- the combination ofa verticallydisposed cylindrical tank having an internally concave bottom with acentral discharge opening 't-herein, a

pump having its intake connected to said tank discharge, a dischargepipe for said pump disposed through said discharge opening centrally andvertically of said tank and provided with a discharge nozzle positionedat the upperend of the tank, and a horizontally disposed concaveforaminated plate disposed above .said nozzle to receive the streamtherefrom. 3. In a stock treating machine, the combination of a tankhaving a discharge at the bottom, a pump having its intake connected tosaid discharge, a discharge pipe for said pump disposed vertically ofsaid tank through said discharge opening, and a horizontally disposedforaminated'member disposed above and in a spaced relation to the end ofsaid discharge pipe to receive the stream therefrom.

4. In a stock treating ,machine, the combination of a tank having adischarge at the bottom, a circulating pump, a dischargepipe for saidpump delivering Within said tank, and. a foramina-ted member disposed inalignment .with the stream delivered by the pump, all coacting for thepurpose specified.

5. In a stock treating machine, the combination of a tank, a stockcirculating pump connected to the bottom of the tank and pro-. videdwlth a discharge nozzle within said "tank, and a concave foraminatedplate disposed transversely of said nozzle to receive the streamtherefrom. 6. In a stock treating machine, the combination of a tank, astock circulating pump connected to the bottom of the tank andprovidedwith a discharge within said tank, a

and a foraminated member'disposed to receive the stream fromsaid'discharge.

In' witness whereof, I have hereunto set my hand and seal in thepresence of a witness.
